BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention generally relates to compounds that may beused to inhibit corrosion of metallic containers, such as those made oftin, aluminum, steel, or a combination thereof. More specifically, thepresent invention relates to such corrosion inhibiting compounds for usein cosmetics and other topically applied products.

[0003] 2. Description of the Prior Art

[0004] Recent legislation and changing consumer preferences have lead tothe development of cosmetics and other topically applied consumerproducts that have lower concentrations of volatile organic compounds(VOCs) compared to similar compositions of merely a decade ago. Ingeneral, newer compositions replace the less favored VOCs with waterand/or other compounds, such as alcohol, that typically contain residualamounts of water. However, water creates a potential for metalliccontainer corrosion that exponentially increases as the water contentincreases.

[0005] The mechanism of corrosion may be uniform, galvanic,intergranular, or concentrated. Such corrosion may manifest itself ascrevice corrosion, pitting, selective leaching, or stress cracking.Corrosion usually occurs electrochemically, involving electron transfersaway from metals that are being oxidized, and electron acceptance bysubstances that are reduced.

[0006] The main approaches to minimize corrosion from fluids in ametallic container are to (1) lower the concentration of oxygen, (2)lower the concentration of corrosive ions, such as chlorides andsulfates, (3) optimize the pH of the composition, (4) utilize corrosioninhibitors, and (5) use a combination of any or all of the previous fourapproaches.

[0007] Corrosion inhibitors may be used as a lining material on theinner surface of the metallic container or canister or may beincorporated into the composition. However, while corrosion inhibitorsmay reduce the rate of overall corrosion, the electrochemical conditionsof the composition may shift such that stress corrosion cracking and/orpitting may occur.

[0008] Many corrosion inhibitors are unsuitable for use in cosmetics andother consumer product compositions because the corrosion inhibitorshave an objectionable effect on the aesthetics and/or function of thecomposition in which it is incorporated. As an obvious example,chromates and dichromates are well known corrosion inhibitors, yet arevery toxic to humans.

[0009] U.S. Pat. No. 3,992,318 to Gaupp, et al. describes a corrosioninhibitor that requires a combination of a water-soluble phosphonic acidor its salt, a water-soluble polyphosphate or alkali metal phosphate,and a water soluble polymer of acrylic acid and/or methacrylic acid. TheGaupp, et al. patent discloses that this corrosion inhibitor is suitablefor aqueous systems, particularly cooling systems for heat-producingequipment.

[0010] U.S. Pat. No. 4,240,925 to Tait discloses a pitting corrosioninhibiting composition that requires a cathodic corrosion inhibitor thatis a phosphoric acid ester, amide or amide-ester, and an anodiccorrosion inhibitor that is an organic compound.

[0011] U.S. Pat. No. 4,052,160 to Cook, et al. discloses the use ofphosphonocarboxylic acids as corrosion inhibitors and/or scale controlagents.

[0012] U.S. Pat. No. 4,548,787 to Wilson et al. discloses compositionsfor inhibiting mineral scale and the corrosion of metals. Thecompositions have water-soluble salts of an acid that can be molybdicacid, tungstic acid, and selenic acids in combination with awater-soluble phosphate.

[0013] Czech Patent No. 262,475 describes single component varnishesthat have, among other ingredients, Group II metal dihydrogenphosphates.

[0014] Czech Patent No. 244,376 describes corrosion inhibitors forclosed water and water-alcohol cooling systems. The corrosion inhibitorshave an inhibitor mixture that includes disodium hydrogen phosphate,sodium metasilicate, and 1,2,3-benzotriazole.

[0015] Chinese Application No. 1,103,655 describes an anticorrosive heattransfer composition for heat pipes. The composition has sodiumhexametaphosphate, trisodium phosphate, and disodium hydrogen phosphate,among other ingredients.

[0016] There is a need for corrosion inhibitors for use in cosmetics andother consumer product compositions that are non-toxic, non-aromatic,invisible, and generally compatible with the extensive variety ofcompounds that are used in cosmetics and other consumer productcompositions.

[0017] Applicants have surprising discovered that phosphate compositionsmay be used in cosmetics and other consumer product compositions toeffectively inhibit corrosion, yet exhibit no undesirable aestheticand/or functional attributes. Specifically, applicants have discoveredthat phosphates and/or polyphosphates are effective in cosmetics andother consumer product compositions when present in an amount about 0.05percentage by weight (wt %) to about 1.5 wt % based on the total weightof the finished composition.

SUMMARY OF THE INVENTION

[0018] It is an object of the present invention to provide a cosmetic orother topical composition having a compound in an amount effective toinhibit corrosion of the composition's metallic container.

[0019] It is another object of the present invention to provide such acorrosion inhibiting compound that is non-toxic, substantiallynon-aromatic, and generally compatible with the finished, topicallyapplied consumer composition.

[0020] Accordingly, there is provided a cosmetic or topical compositionfor use on the human body having a phosphate corrosion inhibitor in anamount effective to inhibit corrosion of metallic containers containingthe composition. Preferably, such a cosmetic or topical composition hassodium hydrogen phosphates and/or sodium polyphosphates in an amountabout 0.05 wt % to about 1.5 wt % based on the total weight of thefinished composition.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The present invention provides an inorganic corrosion inhibitorfor use in cosmetics and other topically applied consumer productcompositions, such as aerosol hair-care products.

[0022] Applicants have surprisingly discovered that phosphate compoundsmay be used as effective corrosion inhibitors in cosmetics and othercompositions that are applied topically to the human body. Inparticular, applicants have surprisingly discovered that topicalcompositions incorporating phosphate compounds as the principlecorrosion inhibiting agent, as opposed to other known corrosioninhibitors, were not impaired either aesthetically or functionally.

[0023] Accordingly, the composition of the present invention should notemploy as the principle corrosion inhibiting agent compounds such asmolybdate, selenate, tungstate, water-soluble silicate,siloxane-silicate copolymer, phosphonic acid, water-soluble polymer ofacrylic and/or methacrylic acid, aluminum phosphate, ε-caprolactam,1,2,3-benzatriazole, or an organic phosphate.

[0024] Phosphate compounds are compounds having at least one phosphategroup (PO₄ ³⁻). Similarly, phosphite compounds are compounds having atleast one phosphite group (PO₃ ³⁻). Polyphosphate compounds are compoundhaving at least one polyphosphate group (P_(x)O_(3x+1) ^((x+2)−)),wherein x is an integer greater than 1, such as a pyrophosphate group(P₂O₇ ⁴⁻). Accordingly, as used herein, unless stated otherwise, theterm “phosphate” also includes phosphite and polyphosphate.

[0025] Preferred phosphate compounds according to the present inventionare phosphate salts of alkali metals (Group IA), such as sodiumphosphate, disodium phosphate, and potassium phosphate. In addition,phosphate compounds for use in a composition according to the presentinvention may also be phosphate salts of alkaline earth metals (GroupIIA), such as magnesium phosphate and calcium phosphate.

[0026] A particularly useful phosphate salt of an alkali metal accordingto the present invention is disodium hydrogen phosphate. Disodiumhydrogen phosphate is used in boiler water treatment, electricalplating, detergent manufacture, metal cleanser, and dye auxiliary. Foodgrade disodium hydrogen phosphate may be used in food treatment as anemulsifier, a nutrition intensifier, a buffer, and powder acidulant.Disodium hydrogen phosphate is also known as dibasic sodium phosphateand secondary sodium phosphate.

[0027] Another phosphate salt of an alkali metal that is particularlyuseful according to the present invention is sodium polyphosphate.Sodium polyphosphate is a mixture of sodium salts of polyphosphoricacid. Sodium polyphosphate is also known as sodium hexametaphosphate andsodium tripolyphosphate.

[0028] The phosphate compound may be present in the composition in anamount about 0.05 wt % to about 1.5 wt % based on the total weight ofthe composition. Preferably, the phosphate compound is present in anamount about 0.1 wt % to about 1.0 wt %, and more preferably about 0.1wt % to about 0.5 wt %, based on the total weight of the composition.These ranges for the phosphate compound are effective for inhibitingcorrosion when incorporated in a composition having water. In addition,these ranges for the phosphate compound are effective when thecomposition has an amount of water about 10 wt % to about 75 wt % basedon the total weight of the composition.

[0029] The compositions of the present invention can be packaged incontainers made from tin, aluminum, steel, or any combination thereof.The compositions of the present invention have been found to beparticularly compatible with aluminum, which has heretofore presented achallenge to prior art, topically applied, consumer productcompositions.

[0030] Tables 1 and 2 summarize the results of a screening process forappropriate corrosion inhibitors. A selected corrosion inhibitor wascombined with a composition having a resin and no more than about 55 wt% VOCs, but without dimethyl ether propellant. The effect and potentialfor corrosion on unlined tin and unlined aluminum were visually assessedusing an optical microscope. The effects and potential for corrosion onunlined tin and unlined aluminum were also assessed by a cyclicpotentiodynamic polarization (CPP) test in accordance with ASTM G61,which is incorporated herein by reference. The CPP test is anaccelerated electrochemical technique that provides an indication of thecorrosion behavior of a metal exposed to a particular environment. Inthis case, a specimen from a metal container is exposed to a hair spraybase formula in the corrosion cell. The potential between the specimenmetal and a reference electrode is controlled and the ensuing current ismeasured. The cell is open to the atmosphere and the test is conductedat ambient temperature.

[0032] As stated above, certain ingredients in cosmetic and othertopically applied consumer product composition will promote corrosionand/or counteract corrosion inhibitors within the composition. Resinsare one such corrosion promoting ingredient. However, some resins areessential to the function of many cosmetic and topically appliedconsumer product compositions. Thus, careful selection of both the resinand corrosion inhibitor is necessary. Resins that may be used in thepresent invention include: acrylates copolymer, PVP-modified resin,vinyl acetate copolymers, vinyl alcohol copolymers, polyurethane filmformers, isobutylene/ethylmaleimide/hydroxyethylmaleinide copolymers,acrylates/succinates/hydroxyesters acrylate copolymer, modifiedcornstarch, low molecular weight esters of PVM/MA copolymer,octylacrylamide/acrylates/butylaminoethyl methacrylate, polyurethanesand other resins that do not require neutralization, and any combinationthereof. Resins that do not require neutralization are most preferred.

[0033] The following formulas are examples according to the presentinvention, which incorporate disodium hydrogen phosphate as a corrosioninhibitor. The compositions of the present invention preferably includean active ingredient selected from the group consisting of: a hair careactive, a skin care active, a nail care active, a foot care active, adeodorant, an antiperspirant, a fragrance, an antimicrobial, anantifungal, an insect repellant, a sunscreen/UV absorber, and anycombination thereof. These ingredients are provided in an amounteffective to achieve the intended purpose of the composition. Thecomposition may be an aerosol or a non-aerosol. When an aerosol, thecomposition may include up to 85% VOC, such as a propellant. Preferably,the composition has VOCs in an amount about 55% by weight or less basedon the total weight of each composition.
